"Think of it like a transcontinental railroad — not the fastest way to move a lot of mass, but certainly the most efficient,” Jared Isaacman said about nuclear electric propulsion.
Solar power has the disadvantage that there's no Sun at night. Satellite startup Reflect Orbital wants to change that, but at what cost?
A preview of the latest novel by the Hugo- and Nebula-winning author.
Inflation's two main criticisms, that it can predict anything and that the "measure problem" remains unsolved, can't erase its successes.
The Orionids meteor shower peaks October 20th/21st here in 2025, coinciding with a new Moon. See the brightest shooting stars of the year!
To learn how our Universe grew up, we have to look at large numbers of galaxies at all distances to find out. Good thing we have JWST!
Our Sun only arose after 9.2 billion years of cosmic history: with many stars living and dying first. How many prior generations were there?
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
Since the time of Galileo, Saturn's rings have remained an unexplained mystery. A new idea may have finally solved the longstanding puzzle.
If AI is modeled only on human intelligence, will it inherit only human ways of seeing the world?
Quantum mechanics was first discovered on small, microscopic scales. 2025's Nobel Prize brings the quantum and large-scale worlds together.
In this excerpt from "Governing Babel," John Wihbey explores how AI is reshaping online moderation by offering tools that can help human moderators, but also raises the risk of disinformation and digital chaos.
In 2025, Earth remains the only planet where life is known to exist. Without a second example, "The Stand" has a vital lesson to teach us.
Behind the plateau in corporate AI lies a surge in personal and agentic use.
By deeply imaging a large volume of space, COSMOS-Web provides JWST's widest cosmic views. Its gravitational lenses reveal a big surprise.
As the Universe ages, it continues to gravitate, form stars, and expand. And yet, all this will someday end. Do we finally understand how?
Welcome to The Nightcrawler — a weekly newsletter from Eric Markowitz covering tech, innovation, and long-term thinking.
From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?
As October begins, thousands of longtime NASA employees are leaving the agency. 4000+ will exit by January 9, 2026, changing NASA forever.
In this excerpt from "The Formula for Better Health," Tom Frieden explores how Alice Hamilton transformed public health in her fight against lead poisoning.
Proposed over 2000 years ago by Democritus, the word atom literally means uncuttable. Revived in 1803, today's "atoms" can indeed be split.
The incredible story of how the US Army began the march toward generative AI in 1943 — and what it means for your business today.
From the Big Bang to a prior period of cosmic inflation, our cosmic origins are clearer than ever. Yet these 5 big mysteries still remain.
If you think of the Big Bang as an explosion, we can trace it back to a single point-of-origin. But what if it happened everywhere at once?
A childhood spent under the spell of sleight-of-hand taught me skepticism, curiosity, and the habit of looking beneath appearances.
Big Think spoke with astronomer David Kipping about technosignatures, "extragalactic SETI," and being a popular science communicator in the YouTube age.
All of the matter that we measure today originated in the hot Big Bang. But even before that, and far into the future, it'll never be empty.
A conversation with Dr. Susan Schneider on the AI risks we’re not talking about and why the fixation on AGI is misplaced.
As we gain new knowledge, our scientific picture of how the Universe works must evolve. This is a feature of the Big Bang, not a bug.
Brian Gumbel — President and Chief Operating Officer (COO) at Dataminr — explores the cutting edge of real-time information analysis.
